Yii2 Serialized Attributes Behavior

This Yii2 model behavior allows you to store arrays in attributes. To attach the behavior put the following code in your model:

    public function behaviors()
    {
        return [
            'serializedAttributes' => [
                'class' => SerializedAttributes::className(),

                // Define the attributes you want to be serialized
                'attributes' => ['serializedData', 'moreSerializedData'],

                // Enable this option if your DB is not in UTF-8
                // (more info at http://www.jackreichert.com/2014/02/02/handling-a-php-unserialize-offset-error/)
                // 'encode' => true,
            ],
        ];
    }
